extracting public key from private key dynamically using M2Crypto

is it possible to extract public key from private key in pem format in python, with something like M2Crypto? I want to same thing happen like when you use this command:

openssl rsa -in mykey.pem -pubout > mykey.pub

Solution

  • M2Crypto.RSA has load_key function which returns an RSA object which has save_pub_key method. 

    from M2Crypto import RSA
RSA.load_key('mykey.pem').save_pub_key('mykey.pub')
